| Abstract |
| X-ray diffraction studies and densification measurements were carried out on three
compositions, 75% Ti02+25% Zr02, 75% Ti02+25% A/20 3, and 100% Ti02,
designated as TZ, T A and T respectively, heated under oxidizing and reducing atmospheres
between 1200"C and 1400°C. The densification was always higher and the formation
of the new phases took place with greater ease when the specimens were fired under
reducing conditions. This was possible due to the formation of anionic vacancies in
the Ti02 structure, which would enhance diffusion. |
